I am trying to write a function that will access a column of a data frame without having to qualify the name of the data frame column as long as the name of the dataframe is passed to the function. As can be seen from the code below, my function is not working:
df <- data.frame(x=1:10,y=11:20) df test <- function(column,data) { print(data$column) } test(x,df) I am trying to model my function after the way that lm works where one needs not qualify column names, i.e. fit1<- lm(y~x,data=df) John David Sorkin M.D., Ph.D. Chief, Biostatistics and Informatics University of Maryland School of Medicine Division of Gerontology Baltimore VA Medical Center 10 North Greene Street GRECC (BT/18/GR) Baltimore, MD 21201-1524 (Phone) 410-605-7119 (Fax) 410-605-7913 (Please call phone number above prior to faxing) Confidentiality Statement: This email message, including any attachments, is for th...{{dropped:6}} ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
